That's a complicated error. The system is using the base descriptions (which usually return "error!") for some starting buildings - you can tell because it says (Western Greek) when it shouldn't in the tooltip passover. We put generic descriptions in for our MIC's and some nomad buildings to get it to look a little better at least. If it's one of those you refer to, a MIC level that is placed at the start of the game, then we can do little to stop it it seems. It's one of the only things that we just scratch our heads and say "we give up" after trying to find out for a year why the game does that to some buildings placed at the start of the game (when they never do that once you are in game and build it).
